tion of mold upon the inner surface of the silo.

The invention essentially comprises the y circular in cross section, constructed of suitable material such as brick and retained in vertically spacedrelation to each other by'ties or headersplaced upon each tier or layer of bricks and arranged to span theintervening space between the walls.

The iiivention also comprises the arrangement of a doorin which the frame sections abutting the edges of the walls are secured by cables placed at predetermined points upon the tiers of the inner wall and fastened to the frame sectioiis as by bolts, and sectional doors detachably secured to the frame sections and adapted to be placed in position as the space within the silo becomes filled. V

For a full understandin of the invention andthe merits t'liereofan also to acquire a knowledge of the detailsofconstruction and the means for eifecting the result, reference is to be had to the following description and the drawings hereto attached. I

While the essential and characteristic features of the invention are necessarily susceptible of modification still'the preferred embodiment of the invention is illustrated" in the accompanying drawings, in which:

Figure. 1 is a front elevation of the improved silo; Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is an enlarged perspective illustrationof one of the door sections; and, Fig. 4 is an enlarged detail View illustrating the method of seciiiring the door frames to the wall of the s as.

' Referring to the drawings the numeral 1 designates one wall of the improved silo preferably constructed of brick or other suitabl'e'material and circular in cross .section. Surrounding the wall land in spaced relation thereto is an exterior wall 2 correspondingl in formation with the firstimentloned wa l and tied to said wall 1 by suitable ties or headers 3 placed upon each layer or tier of brick atintervals as illustrated, in Fig. 2.

These ties or headers may be short lengths 'Ofordinary barbed wire embedded in the mortar upon each tier of bricks and arrangedtospan the intervening space 4 between the walls-.1 and 2, By such an arran ementthe uninterrupted (passage of air in t e space-4 between. said walls is permitted and thus the penetration of moisture to the inner wall 1 and the consequent formation of mold upon the interior is prevented. The inner and outer walls are formed with .vertically disposed registering doorways, and frame sections or j anibs 5 are arranged at the corresponding ends of the walls and extend across the space 4' therebetween, in order to .close the latter. The jambs preferably terminate short of the inner face of the inner wall 1, so that the opposing ends thereof are partially freve'aled, as illustrated in Fig. 2, for, a purposeto bepresently dis- The frame sections are held in place, in the present instance, by cables 6 which may be composed of any suitable number of strands, according as found necessary, and which are embedded in the mortar between predetermined tiers of bricks and are secured at their opposite ends to ring bolts 7 which pass through and engage with the respective frame sections. The cables extend entirely around the inner wall, and therefore serve to hold the frame sections securely in abutting i'elation to the. ends of the walls and against accidental displacement.

The silo is closed by means of a plurality of superposed door sections 8 that are adapted to be fitted between the revealed end portions'of the inner wall, and are designed to be held against the adjacent edges of the frame sections 5 so as to be braced against silo. In the present instance, the door sections are each provided with swinging hooks 9 that are arranged to engage the outer edges of the jambs to retain the door sections in position and admit of their ready detachment when occasion demands. The

'10s the outward pressure of the contents of the manner and adapted to withstand excessive nection with the accompanying drawings, itv

door sections are placed one upon the other in order to build up the door as the interior of the silo is filled.

For convenience, a plurality of strips 11 are secured to the outer edges of the frame sections and serve as rungs of a ladder through the instrumentality of which one may ascend to the top-of the silo.

The elements of the construction-most important in carrying out the present invention, are the formation of the inner and outer walls between which an air space is provided, ofthe method of tying the two walls together without interrupting the pas sage of air between said walls, and the arrangement of sectional doors detachably secur ed to ,theifraine sections, the latter being anchored to the walls in a reinforced essure exerted upon the interior of the inner wall and upon the sectional doors.

From the foregolng description in conwill be'appzirent that an economically constructed srlois, provided, which possesses the elements of simplicity and convenience in use, and which will preserve the sto1'ed ma-' "respective ja'mbs, and means for closing the doorway.

2. A silo embodying a continuous wall constructed in tiers and provided with a vertically disposed doorway, jambs disposed at the opposmg ends of the wall, a cable v placed between sundry of said tiers with its opposite ends fastened to the respective jambs and anchoring the same in position, and means for closmg the doorway.

In testimony whereof I afiix my signature in presence of two witnesses. v
